Ceramic water filters are an inexpensive and effective type of water filter. They rely on the small pore size of ceramic material to filter dirt, debris, and bacteria out of water.

As with most filtration methods, water is carefully introduced to one side of the filter which acts to block the passage of anything larger than the pore size.

Easily breakable so take care when handling.

Ceramic water filters may be treated with silver in a form that will not leach away. The silver helps to kill or incapacitate bacteria and prevent the growth of mold and algae in the body of the filter.

Ceramic filtration does not remove chemical contaminants, per se. However, some manufacturers (especially of ceramic candle filters) incorporate a high-performance activated carbon core inside the ceramic filter cartridge that reduces organic and metallic contaminants. The active carbon absorbs compounds such as chlorine. Filters with active carbon need to be replaced periodically because the carbon becomes clogged with foreign material.

Two most common types of ceramic water filter are pot-type and candle-type filters. Ceramic filter systems consist of a porous ceramic filter that is attached to, or sits on top of a plastic or ceramic receptacle. Contaminated water is poured into a top container. It passes through the filter(s) into the receptacle below. The lower receptacle usually is fitted with a tap.

The filter(s) can be cleaned by brushing them with a soft brush and rinsing them with clean water. Hot water and soap can also be used.
